Mammals Research and Prospect of hair


1987), Xue-min et al (1992), King Songyan et al (1992) description of the animal coat proteins are composed of the difference between the description of the results are. Fur protein composition and the composition, but there are differences with director of instrument according to its composition and the composition of the protein contains different ingredients to be identified to the species. There seems defective. Because the amino acids except l 『affected by genetic factors outside. Kang is also subject to environmental impact factors. Different composition of the ecological environment of the food are not the same. Therefore,[link widoczny dla zalogowanych], animal type and quantity of food intake is also different. Moreover,[link widoczny dla zalogowanych], different types of animal digestive physiology characteristics determine the absorption and build the body embedded Tong G acid type and quantity of ammonia so that only the know the source of animal hair sample health,[link widoczny dla zalogowanych], nutrition, growth stage and gathering seasons conditions. Contained in their hair to a variety of ammonia acid effective than G on the addition, the fee Rong Mei, Jing Songyan et al (1993) 6 kinds of animal hair in the form of pigment granules were compared. Found in different species, there are some differences between most of the studies on animals over the different types of hair to distinguish between r (guard hair, hair). The different parts of the body of the same animals,[link widoczny dla zalogowanych], a comparative study of the hair less. King of the cats loose rock, etc. were studied. They are parts of different animals of the same structure of the hair scales were compared. Found that there is a big difference. Can be used as a basis for classification. Kim Kun, Zhang Qiyuan (2003) in the hair of several differences between cats selected for different parts of the hair. They found differences in scale types exist so we must be considered in the study of Mao's part to take the second, the current outlook. Forest Police in handling cases of wild animals. Easier at the crime scene evidence is collected hair. Thus the research on the hair it is very Xia to the first. Analysis of the protein in hair of wild animals and trace elements. Recognition of the value of species is not particularly great. Because both affected by the environment is relatively large. In some Western countries. With trace elements by animals to determine the species origin of precedent. This incidence of investigators to detect the first site has some value. From the source to contain the destruction of wild animals. So. Can be detected by this analysis to determine the number of sub-species within its distribution area in the coronal Yun Tong, a part of. But this is only the attribution of the species in that post to do. And it is very important to us followed. To extract the DNA in hair identification of species is undoubtedly a very effective method. However, we have obtained no more than hair follicles. Difficult to extract DNA. Both species identification using DNA technology is very expensive third. In the three-tier structure of wool fibers. Medulla pattern types and scales of species are identified as evidence. Gang as they ask the same kinds of individuals but only a slight difference only from a simple hair to know what species it is also quite difficult. Because the lack of appropriate databases to conduct cf often involves the microstructure under the hair to identify species belong. The lack of know the name of the species to study the structure of its pores, which requires a lot of hair we still had more than scales were compared. That is,[link widoczny dla zalogowanych], to build a database of all kinds of animal hair. And computer image processing system with a combination of hair analysis. Construction of the sample library to consider hair to be collected, collecting site, the same species in different parts of the body and with a hairy root hair to the tipping of the scales types. It can be said that the new formulation of old problems. The opposite side from the study of hair. Hair samples to establish the control library, of course. Construction of such a type and scale of various animal hair medulla pattern database is a long process. In addition. Observed pattern of hair medulla. Traditional methods are using optical microscopy or scanning electron microscope to carry out. The former observation ineffective. The latter cost is higher, and polarized light microscopy can resolve the issue. It reflects more clearly the type of pattern hair medulla. Operation is simple and short. Staff from the hair of mammals to distinguish between a practical and effective method. Because animals in the wild is hard to find entities. The hair is easier to get under the hair to identify the mammals. Scale type and pattern of the observed medulla is relatively feasible. Because the hair has some kind of structural features within the specific. And the hair is relatively easy to observe the operation. Therefore, the relatively low cost. Using hair to identify the census of wild animals in the wild animals and wild animals in the detection of cases is a very broad application prospects (Author Nanjing Forest Police College) (Editor Liu Yunjie) FORESTRYPUICSECURITY19
